Editorial review


Pedro Castro Senior editor

Windows operating system can associate a given extension with the program used to open the contained data. This is what allows you not only to open a document using the menu command but also open this document directly from the Files Manager. However, there are times when you download or receive a file that your operating system is unable to recognize.
File Type Assistant can help you open files with unknown extensions. The program integrates with your system and automatically displays a window when an unknown file type is found. Thus, using the program is really easy because choosing the desired option from a menu is all it takes. The first two options imply visiting the developer’s site to either find software to open your file or read about that specific file type. The third option will take you to the default system tool so that you can manually associate your file with already installed applications.

All in all, File Type Assistant is a light and unobtrusive application that solves a commonly found problem. Although Windows comes with a similar built-in tool, it generally fails to find proper associations, mainly when the file types are not very common. File Type Assistant provides the advantage of connecting to a vast online database about file extensions. However, it becomes totally useless when you are not connected to the Internet at the moment.


  • It is very easy to use.
  • It is light.
  • It is backed by a vast Internet database.


  • It becomes useless when you are not online.

Publisher's description

The File Type Assistant from Trusted Software is a little helper application that kicks in when you try to open a file you do not have a viewer or player for.

You can select either to visit the Trusted Software website where we offer safe and tested software that can open the type of file you need a viewer for, or you can let Windows handle it the way it normally does.

You can download it here or you may get it if you download and install other products from this and partner sites. It must always be disclosed in product EULAs if it also installs the File Type Assistant.
